Mailbox Migration Made Simple

An email migration tool is enterprise software that automates the transfer of emails, contacts, calendars, tasks, and other mailbox data between email platforms. It connects to source and destination systems via secure APIs, preserving folder structure, metadata, and permissions while minimizing downtime.

To migrate from Gmail (Google Workspace) to Microsoft 365, connect both tenants to Cloudiway using OAuth 2.0, map users between source and destination, configure migration settings, then run the migration. Emails, contacts, calendars, and Google Drive files can all be migrated together or separately.

Exchange to Office 365 migration is fully automated with Cloudiway. Connect your on-premises Exchange server (2010, 2013, 2016, 2019) and your Microsoft 365 tenant, map mailboxes, and execute the migration. All emails, contacts, calendars, tasks, and permissions are preserved.

A tenant-to-tenant migration moves mailboxes, files, and data between two Microsoft 365 (or Google Workspace) tenants. This is common during mergers, acquisitions, divestitures, or rebranding. Cloudiway handles cross-tenant migrations with full data fidelity and permission mapping.

Yes. Cloudiway supports Lotus Notes (Domino) to Microsoft 365 migration. Emails, contacts, calendars, and archives are extracted from NSF files or live Domino servers and migrated to Exchange Online mailboxes with full metadata preservation.

Zimbra to Microsoft 365 migration connects directly to your Zimbra server via IMAP or native protocols. Cloudiway migrates emails, folders, contacts, and calendars while preserving timestamps and folder structure. Shared mailboxes and distribution lists are also supported.

Migration duration depends on data volume, number of mailboxes, and throttling limits. Cloudiway uses parallel processing to migrate thousands of mailboxes simultaneously. A typical 50GB mailbox migrates in 4-8 hours. Delta sync ensures only new emails are transferred in subsequent passes.

Yes. Cloudiway preserves the complete folder structure, email metadata (dates, read/unread status, flags), attachments, and inline images. Labels in Gmail are converted to folders in Outlook, and vice versa, according to configurable mapping rules.

Cloudiway fully supports shared mailbox migration, including permissions and delegation settings. Distribution lists, security groups, and mail-enabled groups are also migrated with membership intact. Resource mailboxes (rooms, equipment) are handled automatically.

Yes. Cloudiway uses delta sync technology for zero-downtime migration. Users continue sending and receiving emails throughout the process. Multiple sync passes capture all changes, and final cutover is seamless with no mail loss.

Absolutely. Cloudiway uses OAuth 2.0 authentication (no passwords stored), encrypts all data in transit with TLS 1.2+, and is compliant with GDPR, SOC 2, and HIPAA. No email content is stored on Cloudiway servers - data flows directly between source and destination.

Cloudiway offers flexible per-mailbox licensing. Pricing depends on source platform, data volume, and features required. Volume discounts are available for large migrations. Contact sales for a custom quote or start with a free trial to migrate test mailboxes.

Cloudiway has no hard mailbox size limit. We routinely migrate mailboxes of 100 GB or more (the Microsoft 365 maximum), with parallel item-level transfer to keep duration reasonable. Very large mailboxes can be split across multiple migration windows or handled with delta passes so that the final cutover window remains short, even for archive-heavy users.
